Adds crate::os:read_inodes() method to read the output of df -i into a vector of DiskInodeUsages.
A quick word on fixtures/linux/disk_usage/df_garbage: I changed the fixture, as parse_percentage_segment (containing the Err that would make the test pass normally) is not called by parse_df_output anymore; it's called a level up instead.
